Abstract

PURPOSE:To separate a body from a setting and control part in a protective relay testing device, facilitate the carrying of the setting and control part, shorten the test time, and reduce the carriage of heavy cargos. CONSTITUTION:The body of a test voltage and current supplying part occupying the greater part of the weight of a protective relay testing device is separated from the setting and control part of a test element, and they are connected to each other by wire or wireless, or through an optical circuit. Thus, the setting and control of the test element and the connection change of a test terminal can be carried out by a single testing worker required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective relay tester for electric power.

[0002]

2. Description of the Related Art In a conventional protective relay testing device,
The setting / control unit is housed in the main body, and its weight is several 1
It reaches 0 kilograms.

[0003]

Therefore, a protective relay testing device with a large shape and weight is not suitable for movement, and when testing a protective relay, a test line was extended from the testing device and installed in various places in the power equipment. Test voltage / current is applied to the protective relay test terminal. Also, at the protective relay test terminal, the connection of the test line must be frequently changed according to the test element. In the test using such test equipment, there are multiple personnel such as test personnel for setting and controlling the test voltage / current in the test equipment, test personnel for changing the connection of the test line at the test terminals, and personnel for confirming the operation of the protective relay. Test personnel are required. The present invention has been devised so as to solve these drawbacks and to carry out the test by a single person.

[0004]

[Means for Solving the Problem] The setting / control unit of the protective relay test device is separated from the main unit, and the setting / control unit and the main unit are provided.
Connect by wireless or optical line.

[0005]

[Operation] By separating the setting / control unit of the protective relay tester from the main unit, a heavy and heavy unit is fixed to supply a test current of several tens of amperes, and a setting / control unit that is lightweight and portable is provided. It becomes possible to install by installing around the protective relay terminal and test.

[0006]

[Example] A protective relay tester in which a test voltage / current supply device / communication device is installed in a main body, a setting / control unit and a communication terminal are installed in a portable portion, and the main body and the portable portion are connected by a wireless line.

[0007]

By implementing the present invention, setting of test elements
Control and connection change of test terminals can be performed by a single test staff, and it is effective in shortening test time and reducing heavy goods transportation.
